Abstract:The present affiliation policy regime of Ghana’s higher education system has existed for more than two decades. However, empirical studies to examine the policy rhetoric and reality with regard to building quality assurance capacity in mentored institutions appear non-existent. This paper is based on an illustrative qualitative case study undertaken to examine the achievements and challenges of implementing the policy to build internal quality assurance capacities in mentored institutions. The study was guided by Institutional Theory using 12 key informant in-depth interviews and document reviews as data collection sources. The findings indicate a minimal achievement of the policy intent on internal quality assurance capacity building due to key implementation challenges such as a tripartite relationship structure; increasing cost on mentored institutions and increasing workload on mentor institutions. The study concludes that the gap between the policy rhetoric and reality in the studied mentored institutions appears undesirable and requires stakeholders’ attention.
